Leeds Lie Detector Test

10 Key Points Before Undergoing a Lie Detector Test in Leeds with Lie Detectors UK, a recipient of the Best Polygraph Testing Company in the UK accolade and under the stewardship of the UK Polygraph Association’s Director. The fee is £399 at the primary facility and £499 within Leeds.

1. What exactly is the function of a Lie Detector Test in Leeds?

A Polygraph, commonly referred to as a Lie Detector Test, identifies falsehoods by tracking physiological alterations in Leeds. Administered by skilled Polygraph professionals in Leeds, this instrument quantifies responses to structured queries using a certified method. The renowned Leeds firm, Lie Detectors UK, is a trusted and award-winning Lie Detection provider employing only APA and UKPA certified examiners in Leeds.

2. How is the Polygraph Operated?

The Polygraph observes changes in blood pressure, sweat activity, circulation, and upper body motions in the test subject. Typically, the Polygraph Examiner contrasts various reactions to structured questions across multiple evaluations, discerning between genuine and deceptive responses to interpret the charts. Post-analysis, clients receive a report detailing results from the Lie Detectors UK’s qualified examiner overseeing the Lie Detector Test in Leeds.

3. What's the reliability of a Lie Detector Test in Leeds?

Research indicates that when executed by a competent APA professional employing modern tools and methodologies – as all Lie Detectors UK examiners do – a singular issue assessment employing the Utah method can achieve 92-95% precision. Some studies suggest even higher accuracy levels.

4. What's the cost of a Lie Detector Test in Leeds?

Lie Detectors UK offers Lie Detector Tests ranging from £399 to £499. The lesser rate applies at the main office, while the elevated price pertains to home visits or rented nearby facilities. Prices are fixed and all-encompassing. An upfront deposit secures your booking, with the balance payable on testing day. If further tests are deemed necessary, substantial discounts apply. Contact us now for a quotation.

5. What type of queries are preferred and why?

Our preference is a preliminary telephonic consultation to ascertain Polygraph Test appropriateness for your scenario. The most precise method we employ is a singular issue evaluation encompassing three closely related questions, ensuring optimal accuracy. We focus on factual questions, excluding emotional or intent-based ones. Lie Detectors UK’s examiners in Leeds also anticipate potential excuses for failing the Lie Detector Test in Leeds.

6. Question Formulation Techniques for Lie Detector Evaluations

Throughout the Lie Detector Test in Leeds, three distinct question types are posed by the examiner. Lie Detectors UK adheres to accuracy guidelines, crafting directed lie comparisons, irrelevant, and pertinent questions tailored to each case. The examiner collaborates with you to generate the most appropriate questions, ensuring consensus before proceeding.

7. The Pre-test Discussion

Before commencing the Lie Detector Test in Leeds, a preliminary interview is held, spanning up to an hour. This session facilitates a comprehensive case discussion, familiarizes clients with the process, and addresses queries. A rudimentary Polygraph Test is introduced, offering an experiential preview. This step allows the examiner to make minor adjustments for improved chart results. Each question is then reviewed for clarity.

8. Compilation and Analysis of Data in Leeds

At least three charts are generated per subject, with questions presented in varying sequences. Results are averaged to reach a conclusion. The Leeds-based Lie Detector examiner conducts a comprehensive data review before announcing results, which may indicate truthfulness, deception, or inconclusiveness. Outcomes are shared verbally, complemented by a detailed report available for home delivery upon request.

9. Age and Pregnancy Criteria for a Leeds Polygraph Test?

We cater to individuals as young as 14, but those under 18 require complete parental consent and a maturity assessment. Pregnant women can be tested, contingent upon a complication-free pregnancy.

10. Polygraph's Origins and Evolution

In 1906, the Lie Detector Test was conceptualized by James McKenzie, a Scottish surgeon. The crux of this innovation was monitoring sweat and heartbeat fluctuations. Later, in 1921, John Larson, an American law enforcement officer, refined the Polygraph for forensic applications. By 1925, Leonarde Keeler had further advanced the device, replacing the smoke paper with ink pens for enhanced efficacy.

Accurate Results From a Lie Detector Test in Leeds

Reliability of a Lie Detector Test in Leeds When the appropriate tools, qualified examiners, and correct queries are utilised, polygraph assessments in Leeds can achieve a precision rate of up to 95%. Lie Detectors UK ensures that when conducting a Lie Detector Test in Leeds, we strictly adhere to the single issue approach to maximise the accuracy potential. The credibility can be undermined by inadequate questions, an untrained examiner, outdated devices, or an unsuitable testing environment.

Does Anxiety Influence the Test Outcome? Certainly not. We often address this misconception. A person will naturally exhibit anxiety from the beginning to the end of the evaluation, but our focus is on responses to specific questions rather than overall nervousness. Simply put, if anxiety skewed results, the majority would not pass, whereas we witness a pass percentage close to 80%. The Polygraph Examiner in Leeds is dedicated to ensuring a relaxed and straightforward experience for you.

The Role of Control Questions Control questions serve as a physiological reference point when used by Lie Detector’s UK Examiners in Leeds. These are leveraged to draw parallels with primary questions, aiding in the determination of deceit. Competent examiners typically rely on the Directed Lie Technique when finalising the most apt questions for evaluation. Before undergoing a Polygraph Test in Leeds, all questions are thoroughly deliberated with the participant.

Understanding Eye-tracking

There’s a method that measures pupil fluctuations, yet its 85% accuracy is inferior to a Polygraph Test. Lie Detection via eye-tracking scrutinises minuscule eye motions to gauge the truthfulness of a subject’s responses to certain queries.

Voice Stress Examination

Voice Stress Analysis, though once popular, has been largely debunked due to its inconsistency. It evaluates shifts in voice’s loudness, tone, and resonance.

Brain Activity Monitoring

Functional MRI depicts the brain’s oxygen consumption, spotlighting specific regions to discern the veracity of a subject’s statements. Its reliability, however, is questionable.

Facial Expressions Assessment

High-speed cameras capture fleeting or involuntary facial cues. These micro-expressions can hint at honest or deceptive tendencies, but their efficacy is not consistently proven.


Historically, substances like Ethanol, Sodium Thiopental, and Cannabis have been administered in attempts to extract candid information. Though numerous drugs have been trialled, none universally guarantee truth extraction.

Frequently Asked Questions

Although the UK Government employs over 40 Polygraph Examiners for evaluating probationary sex offenders and terror suspects, UK Courts currently don’t consider reports from Private Polygraph Examiners. Our primary clientele at Lie Detectors UK comprises private and business entities both within the UK and overseas. A significant portion of our tasks at Lie Detectors UK revolves around relationships. However, we also address theft, allegations, and various other scenarios, including Pre-Employment cases involving Leeds Lie Detector.

Commonly referred to as a Lie Detector, a Polygraph captures the physiological reflexes of an individual in response to questions. This encompasses metrics like blood circulation and pressure, heart rate, breathing, skin conductance, and physical activity.

Undergoing a Polygraph Test in Leeds is entirely pain-free. A slight discomfort might arise due to the blood pressure cuff, but each assessment only lasts between three and four minutes.

The total duration can vary based on the case specifics and the individual examined. Generally, the process lasts approximately two hours, with a minimum duration of ninety minutes. This spans across three phases: pre-test, actual examination, and post-test.

Post-examination, the results are communicated verbally, assuming the Leeds Examiner doesn’t seek an additional opinion. This grants you an opportunity to have an exhaustive discussion with the Lie Detectors UK Examiner in Leeds. A comprehensive report is then made available either via email or printed format, or both if desired. If on-site printing isn’t feasible, a mailed version is dispatched free of charge.

Scheduling a Lie Detector Test in Leeds, UK is straightforward, swift, and confidential. Ideally, we engage in a conversation before confirming a booking to determine the suitability of a Polygraph Test for your case. An upfront, non-refundable payment of £150 is required, post which you’ll receive booking confirmation for Leeds, inclusive of the venue and examiner details. Direct online booking is also an option on our website.

The focus isn’t necessarily the quantity of questions but rather the nature of the issue. We favour single-issue tests to ensure peak accuracy during a Lie Detector Test in Leeds. A reduction in question count doesn’t equate to a cost reduction. Multi-issue tests, where numerous issues are addressed, compromise accuracy. At Lie Detectors UK, we generally avoid such tests, informing clients about potential accuracy discrepancies when we do opt for them.

A non-refundable deposit of £150 is mandated when booking a Lie Detector Test in Leeds. This ensures that the person being tested is genuinely committed to undergoing the Lie Detector Test in Leeds.

I never thought I'd be put in a position to have to do a lie detector test but after 6years of being accused of cheating I decided to do the test for my own peace of mind. I had visions of the jeremy Kyle show but everything was explained to me and Jason put me at as much ease as he could. After getting the true result I wanted it cleared my name and made me realise the whole issue was deeper within my partner as he made every excuse to not believe the test. The test is 100% accurate as I could not control what my body was doing it will only give a result of lying if you are lying. Jason was brilliant with aftercare to myself and my partner and I cannot thank him enough for what he done. Finally i have closure that I needed and I recommend anybody to do this test and with this company if you are ever in that position I found myself in!

Got in touch to ask about taking a lie detector test due to problems within a relationship I was part of. Jason was great with comms, honest and sincere after I explained my predicament to him. His honesty stretched to the point where we both agreed that taking the test wasn’t in my best interests due to the circumstances I am in and for me that’s highly commendable. Thank you Jason, integrity is high on my agenda and I can safely say it is on yours too after our recent comms.

Could not have been any happier with the service. Jason was informative and friendly from the off and did everything he could to make everybody feel comfortable and at ease.
